Read full descriptionHide full description
NinjamZap brings real-time online jamming to iPhone, iPad and Mac — with live video. Connect to any NINJAM server, pick a username, and play music with people around the world. Free, no ads, no studio required. NINJAM is a proven protocol for internet music collaboration, used by musicians for over 15 years. Instead of fighting network latency, NINJAM embraces it: everyone plays along to a shared metronome, and you hear what others played in the previous interval. The result is a surprisingly natural and creative way to make music together. NinjamZap is the first native NINJAM client for iPhone, iPad and Mac, and the first NINJAM client of any kind with live video. LIVE VIDEO (NinjamZap rooms only) - See every musician you're jamming with, frame-locked to the jam interval - Voice chat: talk face to face between songs, then get back to playing - HD up to 1280x720 per tile, with quality that adapts to the room - External display output for the video grid, one-tap full screen - Built-in, USB and Continuity cameras JAMMING & AUDIO - Connect to any public or private NINJAM room and start playing - Multi-channel: up to 8 local channels (mono or stereo) for your whole rig — guitar, bass, vocals, drums, synths - A mixer for the whole band: volume, pan, mute and solo for every musician and channel - USB audio interfaces — iRig, MOTU, Focusrite, Behringer and more - Audio FX per channel: reverb, compressor and mic boost - Room key detection: see the key the band is playing in - Session recording at 256 kbps AAC, metronome-free and ready for your DAW - Vorbis quality presets from Quick (64 kbps) to Studio (256 kbps) - Latency profiles from Ultra Low (3 ms) to Safe (10 ms) BRING YOUR WHOLE RIG - AUv3 Send: route synths, effects and plugins from AUM straight into your session - LAN Companion: use a second phone, a laptop or our desktop plugin as a wireless input over Wi-Fi - Ableton Link: your apps follow the room's tempo - MIDI Clock Out: sync drum machines, synths and DAWs to the room - BPM/BPI voting and tap tempo SESSIONS & COMMUNITY - Guest mode: no account needed, pick a username and you're in - Sign in for free to send video, use FX and add channels - Browse public rooms and see who's playing, with photos, flags and instruments - Musician profiles: photo, bio, city and instruments - Live chat with links, translations and replies - Report and block users, community rules and a chat profanity filter - On Mac: keyboard shortcuts, resizable chat and a full mixer view HOW IT WORKS 1.

NinjamZap is an independent client, not affiliated with Cockos or the official NINJAM project. Live video is a NinjamZap extension, only available on NinjamZap-hosted rooms; other NINJAM clients ignore video channels and audio still works for everyone. The core audio engine is open source under GPL v3 at github.com/jacinside/ninjamzap-core. Works with any standard NINJAM server. Free, no ads, no in-app purchases.
